. SELF-HEATING. FLAT-1.301%.

DANIEL W. YoUNG, Jr, and Anonsr (3. Donnicri, citizens of the United States, and residents ct Chicago,- in the county oftlook' end tats ot' Illinois,-have invented certain new and useful Improvements 111 ;S51 f-Hfiaillllg,

Flat-Irons, of which thefollowing is a. full, clear, and exact specification. r

Our invention is concerned with self-heating fiat-irons, and is designed to produce e device of; the class described that shall he provided with an efiicient vaporizer and burner for hydrocarbons so that it can be used indefinitely, even with the most difiicult of such oils, such, for instance, as kerosons, to burn which it is more especially designed. A

To this end, our invention consists in cer tain novel features and combinations, all of which will, be fully described in the following speoificetion,- and more particularly pointed 0111: in the claims.

To illustrate our invention, we annex- .hereto three sheets of draw1ngs,.m which the some reference characters are used to designate identical parts in an the figures,

the burner-plate 82 to hold the deflectorplate in position. The burner-plate 82 is a metal screen preferably formed by punching apertures therein with the rough edges downward, and it is shaped to lit in and fill the boat-shaped bottom of theburner-casting, which is formed by a downwardly extending flange 83. This flange 83 has the Central four or" which coiiperate with the recesses 85 formed in the edges of the deflector-plate to position the latter. The lower ends of these flanges 84 form seats for the screen or burner plate 82, and when the parts. are assembled, the lugs 86 formed on in place; and when it is clamped in (place, its coiiperation with the lugs 81 on the efiectordefiectorrplate is provided with a plurality of apertures 87 so that when the iron is ally, the first vapor started, and the generator is hot enough to vaporize, the needle-valve is opened gradupassing ontbeing deflected back through the sub-flame burneropening 79, and as more vapor is turned on,

the excess passes down through-the apertures 87 in the deflector-plate and through apertures '88 nnched in the burner-plate 82, so that a solidjflame is formed on the bottom of said plate. A set screw 89, or some similar lug, serves to supportthe inner end of the burhencasting in place, and the plate -32 rests onfthe lugs QOand 83 formed on the n per surface thereof, so that the parts are properly held in place.

The operation of the above-described ap-, aratus will of'course be readily understood, y those skilled in the art, from the foregoing description of its structure, and we have found by extended experiments that an iron, constructed as herein shown and described will operate satisfactorily for a. long period of time, and canbe readily cleaned and he i; in order.

, Whi e we have shown and described our invention as embfidied in the form which {went present consider best adapted to carry outrits pufposes, it will beunderstood that fit-iscap'able of modifications, and that we do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art. 6
